Razor blade changer



June 1954 J. M. AUSTIN RAZOR BLADE CHANGER Filed June 3, 1950 PatentedJune 1, 1954 UNITED STATES TENT ()FFICE 7 Claims.

This invention relates to razor blade changers.

It is an object of the invention to provide a blade changer ofinexpensive construction, but which is adapted to performing anautomatic blade change with certainty and simplicity of operation.

With this and still other objects which will appear in the followingfull description in mind, the invention consists in the combinations andarrangements of parts and details of construction which will now firstbe fully described with reference to the accompanying drawing and thenbe more particularly pointed out in the appended claims.

In the drawing:

Fig. 1 is a plan view of a blade changer with new and used blademagazines and a razor in place thereon;

Fig. 2 is a section in the line 2-2 of Fig. 1;

Fig. 3 is a plan view of the blade changer of Fig. 1, with magazines andrazor removed; and

Fig. 4 is a section on the line 44 of Fig. 1.

In my application Ser. No. 159,038, filed April 29, 1950, for BladeChanger, I have disclosed a blade changer, razor and magazines for usetherewith. The present invention is an improvement thereon, the objectsbeing to simplify the razor construction and provide a blade changer ofsimple construction which is adapted to mounting on a wall and requiresno box or housing. The details of the magazines and the movement ofparts in changing blades are disclosed fully in my said previousapplication and will be repeated only to the extent necessary to a fullunderstanding of the present invention.

The complete equipment includes the blade changer frame A, razor B andnew and used blade magazines and D.

The frame A is formed from a sheet metal blank by stamping and similarpower press operations. Projections l, 2, 3 and 4 are struck up forholding the magazines, as indicated. Aperture 5 accommodates a tongue 6on the magazine, the tongue 6 fitting under the plate A for holding downthe magazine. Projection 4 is formed as a clip which snaps over anextension I at the other end of the magazine. The end wall 8 of themagazine is firmly held against projection I to position the magazinewith reference to the razor B.

Razor B comprises a handle ID in which are fixed the back member H andguard member I2, the parts being held together with handle I0 andferrule it, as by a rivet I 4. Projections or lugs IE on the guardextend through apertures 16 in the back so that when the razor ispositioned as shown in Figs. 1 and 2 the supporting plate A will engagethe lugs 15, forcing the guard 12 away from the back I! so as to releasethe blade. A tongue H is formed on the back and passes through anaperture [8 in the guard, hooking under the upper edge of this apertureas shown for holding the guard in position at this point. When lugs l5are engaged as shown in Fig. 2 the upper end of the guard will pivot ontongue ll, so that the corner lugs IS on the guard disengage the blade20, permitting sliding of the blade out of the razor by movementparallel to its cutting edge and reception of a new blade by a likesliding movement. It has been found that, if the guard I2 is made ofsufficiently springy metal, a separate spring element for urging theback and guard together may be dispensed with. There is thus produced anexceptionally simple razor having only two parts, apart from the handlestructure.

The means for holding the razor on the blade changer plate A compriseshooks or ledges 2| fitting over the cap portion 22 of the back ll; clip23 passing through aperture IS on the guard and a registered aperture inthe back so as to snap over tongue I! and hold the back down on theplate A; and an abutment 23 for supporting the back ll down toward thehandle Ill. The razor is inserted in the blade changer by placing thecap under ledges 2| and then forcing the handle down until clip 23catches. The razor is removed by reversing these movements, firstlifting the handle to disengage from clip 23 and then sliding the capout from under ledges 2|.

Brackets 26 carry a rod 21 on which is slidably and pivotably mounted apusher 28. Pusher 28 has a tongue 29 adapted to enter a slot in themagazine C and to engage against the back end of the top blade of astack of blades. Details of this structure are fully shown in my abovementioned application and will not be repeated herein. Part of thepusher is struck up at an angle, as indicated at 30, to facilitateoperation by the thumb or finger.

Each time the pusher is operated from right to left, a new blade isinjected in the razor B from magazine C, pushing the used blade from therazor into magazine D. When the magazine 0 is exhausted and the magazineD is filled with used blades, the latter is discarded and the emptymagazine C is placed in the position previously occupied by magazine D.A full new blade magazine may now be placed in the location previouslyoccupied by new blade magazine 0. The slot razor and, in the position ofmagazine D, the

slot 24 is in line with the blade in the razor.

In order to provide space for the extensions 6 of the magazines and tostiffen the plate A and arrange it at a proper angle, a rear flange wall3| is'bent' down'from the' plate as'wel1 as 110 end flange walls"1122.The latter are made triangular in form, as shown, for locating plate Aand a razor carried thereon at a. desired angle.

The plate A, may be held in the hand or.rested-- on a table while theblade change is being made, but is intended for mounting on a wallrasima bathroom.
